systemd-mount may be used to create and start a transient .mount or
.automount unit of the file system WHAT on the mount point WHERE.
In many ways, systemd-mount is similar to the lower-level mount(8)
command, however instead of executing the mount operation directly
and immediately, systemd-mount schedules it through the service
manager job queue, so that it may pull in further dependencies (such
as parent mounts, or a file system checker to execute a priori), and
may make use of the auto-mounting logic.
The command takes either one or two arguments. If only one argument
is specified it should refer to a block device containing a file
system (e.g. "/dev/sdb1"), which is then probed for a label and
other metadata, and is mounted to a directory whose name is generated
from the label. In this mode the block device must exist at the time
of invocation of the command, so that it may be probed. If the device
is found to be a removable block device (e.g. a USB stick) an
automount point instead of a regular mount point is created (i.e. the
--automount= option is implied, see below).
If two arguments are specified the first indicates the mount source
(the WHAT) and the second indicates the path to mount it on (the
WHERE). In this mode no probing of the source is attempted, and a
backing device node doesn't have to exist yet. However, if this mode
is combined with --discover, device node probing for additional
metadata is enabled, and – much like in the single-argument case
discussed above – the specified device has to exist at the time of
invocation of the command.
Use the --list command to show a terse table of all local, known
block devices with file systems that may be mounted with this
command.
systemd-umount can be used to unmount a mount or automount point. It
is the same as systemd-mount--unmount.

The following options are understood:
--no-block
Do not synchronously wait for the requested operation to finish.
If this is not specified, the job will be verified, enqueued and
systemd-mount will wait until the mount or automount unit's
start-up is completed. By passing this argument, it is only
verified and enqueued.
--no-pager
Do not pipe output into a pager.
--no-ask-password
Do not query the user for authentication for privileged
operations.
--quiet, -q
Suppresses additional informational output while running.
--discover
Enable probing of the mount source. This switch is implied if a
single argument is specified on the command line. If passed,
additional metadata is read from the device to enhance the unit
to create. For example, a descriptive string for the transient
units is generated from the file system label and device model.
Moreover if a removable block device (e.g. USB stick) is detected
an automount unit instead of a regular mount unit is created,
with a short idle time-out, in order to ensure the file-system is
placed in a clean state quickly after each access.
--type=, -t
Specifies the file system type to mount (e.g. "vfat", "ext4",
...). If omitted (or set to "auto") the file system is determined
automatically.
--options=, -o
Additional mount options for the mount point.
--fsck=
Takes a boolean argument, defaults to on. Controls whether to run
a file system check immediately before the mount operation. In
the automount case (see --automount= below) the check will be run
the moment the first access to the device is made, which might
slightly delay the access.
--description=
Provide a description for the mount or automount unit. See
Description= in systemd.unit(5).
--property=, -p
Sets a unit property for the mount unit that is created. This
takes an assignment in the same format as systemctl(1)'s
set-property command.
--automount=
Takes a boolean argument. Controls whether to create an automount
point or a regular mount point. If true an automount point is
created that is backed by the actual file system at the time of
first access. If false a plain mount point is created that is
backed by the actual file system immediately. Automount points
have the benefit that the file system stays unmounted and hence
in clean state until it is first accessed. In automount mode the
--timeout-idle-sec= switch (see below) may be used to ensure the
mount point is unmounted automatically after the last access and
an idle period passed.
If this switch is not specified it defaults to false. If not
specified and --discover is used (or only a single argument
passed, which implies --discover, see above), and the file system
block device is detected to be removable, it is set to true, in
order to increase the chance that the file system is in a fully
clean state if the device is unplugged abruptly.
-A
Equivalent to --automount=yes.
--timeout-idle-sec=
Takes a time value that controls the idle timeout in automount
mode. If set to "infinity" (the default) no automatic unmounts
are done. Otherwise the file system backing the automount point
is detached after the last access and the idle timeout passed.
See systemd.time(7) for details on the time syntax supported.
This option has no effect if only a regular mount is established,
and automounting is not used.
Note that if --discover is used (or only a single argument
passed, which implies --discover, see above), and the file system
block device is detected to be removable, --timeout-idle-sec=1s
is implied.
--automount-property=
Similar to --property=, but applies additional properties to the
automount unit created, instead of the mount unit.
--bind-device=
Takes a boolean argument, defaults to off. This option only has
an effect in automount mode, and controls whether the automount
unit shall be bound to the backing device's lifetime. If enabled,
the automount point will be removed automatically when the
backing device vanishes. If disabled the automount point stays
around, and subsequent accesses will block until backing device
is replugged. This option has no effect in case of non-device
mounts, such as network or virtual file system mounts.
Note that if --discover is used (or only a single argument
passed, which implies --discover, see above), and the file system
block device is detected to be removable, this option is implied.
--list
Instead of establishing a mount or automount point, print a terse
list of block devices containing file systems that may be mounted
with "systemd-mount", along with useful metadata such as labels,
etc.
-u, --umount
Stop the mount and automount units corresponding to the specified
mount points WHERE or the devices WHAT. systemd-mount with this
option or systemd-umount can take multiple arguments which can be
mount points, devices, /etc/fstab style node names, or backing
files corresponding to loop devices, like systemd-mount --umount/path/to/umount /dev/sda1 UUID=xxxxxx-xxxx LABEL=xxxxx/path/to/disk.img.
--user
Talk to the service manager of the calling user, rather than the
service manager of the system.
--system
Talk to the service manager of the system. This is the implied
default.
-H, --host=
Execute the operation remotely. Specify a hostname, or a username
and hostname separated by "@", to connect to. The hostname may
optionally be suffixed by a container name, separated by ":",
which connects directly to a specific container on the specified
host. This will use SSH to talk to the remote machine manager
instance. Container names may be enumerated with machinectl -HHOST.
-M, --machine=
Execute operation on a local container. Specify a container name
to connect to.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.

If --discover is used, systemd-mount honors a couple of additional
udev properties of block devices:
SYSTEMD_MOUNT_OPTIONS=
The mount options to use, if --options= is not used.
SYSTEMD_MOUNT_WHERE=
The file system path to place the mount point at, instead of the
automatically generated one.
